Rotation Counter Clockwise

programming flash

Hello guys,

im in a little trouble here =)

Have tried so many times to make this cannon turning other side, looking for formulas, maths, physics, but nothing works until now. So, here im to ask you one more time.

My code:

stop();

import mx.transitions.Tween;
import mx.transitions.easing.*;
easeTime = .5;

map.onRelease = function()
{
	angle_ini = tank_mc.tank_gfx._rotation;
	angle_end = Math.round(Math.atan2(tank_mc._ymouse, tank_mc._xmouse) * 180 / Math.PI);
	
	new Tween(tank_mc.tank_gfx, "_rotation", Regular.easeIn, angle_ini, angle_end, easeTime, true);
}

What do this do? Simple, when click on the map, i get the current angle of the turret, and rotate it to the clicked angle.

Whats the problem? Flash… Always, the flash :angel:

Look the cartesian

Top left: -180
Top Right: 0

Bottom Left: 180
Bottom Right: 0

So, if the tank angle is 170º, and i click on the top left area (-170) instead he go the way up (171, 172, 173, … 179, 180, -179, -178, … -170) it is goes all the way wrong.

Not wrong, but the way that the tween suppose to go. I see the senocular pizza tutorial, but not solve my problem… Anothers rotation question is only “be” at new rotate, not the rotation itself…

Thanks in advance

Solved :bu:

Just changing some actions:

stop();

import mx.transitions.Tween;
import mx.transitions.easing.*;
easeTime = .5;

map.onRelease = function()
{
	angle_ini = tank_mc._rotation;
	angle_end = Math.round(Math.atan2(tank_mc._ymouse, tank_mc._xmouse) * 180 / Math.PI);
	
	new Tween(tank_mc, "_rotation", Regular.easeIn, angle_ini, (angle_ini + angle_end), easeTime, true);
}

I was rotating a movie clip inside the tank_mc, and always getting the angle again from root, now, i only get the “rotate variation”

Anyway, if there is a way to solve the another way, i’ld appreciate :snug:
